Transformers: Ghosts of Yesterday is a mass market paperback novel that serves as prequel to the live-action Transformers film.
- For further information, see Wikipedia's entry on the novel.
Set in 1969 just after the Apollo 11 moon launch, the novel revolves around Sector Seven's attempted transport of the Ice Man and the ill-fated test of an Ice Man-derived spacecraft, Ghost 1, which pulls a Farscape and gets a preview of what's coming Earth's way in July 2007.
- The novel was originally announced as being written by David Cian but after turning in a (self-admittedly  rushed) first draft he was replaced by Alan Dean Foster who then rewrote the novel to an unknown extent. Foster is the lone name on the binding, while Cian receives a story credit inside.
- The book as published only marginally resembles Cian's description of the one he was writing, and features a much more defined scope and focus.
- Much of the plot takes place on a planet reminiscent of the setting of Dune; desert environment, pillars with glyphs carved into them, sandworms, etc.
